Happy Aquarium's own SpongeBob SquarePants

His name's Scrub Rob, and you can find him under the yellow star tab in the Special section of the Happy Aquarium store. Clearly a knock-off of SpongeBob SquarePants, a fan of the show might grab him for the novelty alone, if they're willing to pay up the 58 Facebook Credits (equivalent to $5.80 USD) or 70 Pearls for the honor.

For non-fans such as myself, it would've been nice it they added some functionality to the character. I mean, he looks like a giant scouring pad, which means he looks like the perfect thing to wipe off algae from a tank. But alas, he's just there to look spongey and rock those shades.

Either way, Happy Aquarium expects him to be popular, so he'll only be around until April 29th, 2:00 p.m. PST.
